Title: How about adding HTTP compression option/feature ?
Post by: Rafi on October 04, 2004, 06:14:27 PM

Here is a link to this free software :
http://www.mozilla.org/projects/apache/gzip/

Is it good for HFS ?

Ahha , already there...  :#) Does it apply only to "Browsing" or auto-compressing the downloads ?

That only applies to pages served by HFS.

I'm talking about downloading FILES.
Try downloading this example - http://allmacintosh.xs4all.nl/files/mozilla-mac-1.8a4.dmg.gz . I reach at least x4 times my max bandwidth (~6400Kbps...)

there's no need to compress already compressed files.
a .gz file is already compressed, with the same algo it would be used by the http-compression (that is zlib).
i don't know why your software is saying you are downloading faster, but http-compression is not helping for sure in a gzip file.
mp3, jpg, pdf, etc already use optimized compression that gets better results than http-compression.
http-compression has been introduced to help transfering text based files.
trying to compress a 10MB mp3 before sending it is just a waste of CPU.

every word you say is correct,  but I'm having a hard time to explain why in IE6 - the file/link I gave above and this  link (same file from a different server-site)
http://bihnet.mac.tucows.com/files/mozilla-mac-1.8a4.dmg.gz
are loading at different speed and time in IE6 (the last one at about the "correct" slow speed of my 1.5MBps connection) ...  :?

BTW - getright - loads both at the same speed.

Here are interesting screen-shots...

http://allmacintosh.xs4all.nl/files/mozilla-mac-1.8a4.dmg.gz
~85K/s

http://bihnet.mac.tucows.com/files/mozilla-mac-1.8a4.dmg.gz
~75K/s

You might have some kind of caching software so you are loading the file much faster.

Not that I know of, but maybe. so why is it not working on both ?

anyway, never trust the speed IE displays

do you want to know your dowloading speed? use a software that monitors it. i use tinyresmeter.

Again - correct. I don't ! Other meers (I use DU Meter) do show a "correct" speed. But (a big but...) I'm measuring total download time, and what can I tell you - it is 3-5 times shorter... :?

PS -
Where can I download the TimeResMeter with net traffic display ? The published version (V 0.95a) seems not to include this feature :cry:
